说明：  大规模对抗代码，有追逃，有需要的可以看看(Python code about Against. You can download if you need.)

利用三层卷积神经网络识别信号星座图，准确识别8psk，16psk，32psk，64qpsk四种调制方式，在低信噪比的情况下已然有良好的识别率。(The three layer convolution neural network is used to identify signal constellation, and accurately identify four modulation modes of 8PSK, 16PSK, 32psk and 64qpsk. It has a good recognition rate under low SNR.)

基于UCF101数据集的识别，与实时动作定位(realtime-action-detection)

用Python3在jupyter notebook实现最小二乘法，梯度下降法和牛顿法(Using Python3 to realize least square method, gradient descent method and Newton method in jupyter notebook)

说明：  基于内容的图像检索。通过Bag of Visual Words视觉词袋模型构建视觉词袋，实现以图搜图(Content-based image retrieval.Construct visual word bag through bag of visual words visual word bag model to search for pictures.)

说明：  用于网页大麦网抢票脚本，用于演唱会门票，剧院门票等(damaiwang Concert ticket)

编程规范是重中之重，带你书写良好的变成习惯(It is used to measure noise and detect road noise pollution. It is accurate and has good effect.)

This book is also about complexity science, which is an interdisciplinary field—at the intersection of mathematics, computer science and natural science—that focuses on discrete models of physical systems. In particular, it focuses on complex systems, which are systems with many interacting components.

1. 以身高为例，画出男女生身高的直方图并做对比； 2. 采用最大似然估计方法，求男女生身高以及体重分布的参数； 3. 采用贝叶斯估计方法，求男女生身高以及体重分布的参数（注明自己选定的参数情况）； 4. 采用最小错误率贝叶斯决策，画出类别判定的决策面。并判断某样本的身高体重分别为(160,45)时应该属于男生还是女生？为(178,70)时呢？(1. Take the height as an example, draw the histogram of the height of boys and girls and make a comparison. 2. Using the maximum likelihood estimation method, the parameters of height and weight distribution of male and female students are obtained. 3. Using Bayesian estimation method, the parameters of height and weight distribution of male and female students were calculated (indicating the parameters selected by themselves). 4. Using Bayesian decision-making with minimum error rate, the decision-making surface of category decision-making is drawn. When the height and weight of a sample are (160,45), should it belong to boys or girls? For (178,70)?)

说明：  视频跟踪是计算机视觉中的一个重要研究方向，有着广泛的应用，如：视频监控，人机交互， 无人驾驶等。过去二三十年视觉目标跟踪技术取得了长足的进步，特别是最近两年利用深度学习的目标跟踪方法取得了令人满意的效果，使目标跟踪技术获得了突破性的进展。本文旨在简要介绍：目标跟踪的基本流程与框架，目标跟踪存在的挑战，目标跟踪相关方法，以及目标跟踪最新的进展等，此次资料能够帮助初学者对于这个领域有一个初步的认识。(Video tracking is an important research direction in computer vision and has a wide range of applications, such as: video surveillance, human-computer interaction, and unmanned driving. The visual target tracking technology has made great progress in the past two or three decades, especially the target tracking method using deep learning in the past two years has achieved satisfactory results, making the target tracking technology a breakthrough. This article aims to briefly introduce: the basic process and framework of target tracking, the challenges of target tracking, related methods of target tracking, and the latest progress of target tracking. This information can help beginners to have a preliminary understanding of this field.)
